ATHENA Forged 4T Racing Piston 87.96mm

The 4T Racing ATHENA forged piston with a diameter of 87.96 mm represents engineering excellence in the motorcycle world. With over 40 years of experience, ATHENA has established itself as a leader in the motorcycle spare parts sector, offering hot-forged pistons through an innovative reverse extrusion process. Each piston is made using state-of-the-art CNC (Computer Numerical Control) machines, ensuring production dimensional tolerances of less than 0.01 mm.

Designed in Italy by the ATHENA Research and Development team, this piston is produced from a special aluminum alloy based on silicon, which ensures reliability comparable to that of original components, but with superior strength and optimized performance. The precisely polished profiles promote smooth flow and ideal flame front propagation, enhancing engine efficiency.

The kit includes not only the piston but also the pin, circlips, and the ring kit, all designed to be easily replaceable and interchangeable. It is important to note that ATHENA products intended for displacements and power outputs exceeding those allowed by the road code of the user's country are designed exclusively for competitive use. ATHENA does not assume any responsibility for the use of the product in violation of national regulations.
